Machine for producing rice seed rope and field experiment

It is difficulty for the mechanized planting of rice to be applied in some regions of China,so a prototype of novel machine for producing rice seed rope was designed.It consisted of sending paper strip mechanism,measuring mechanism,twisting paper strip mechanism and rolling seed rope mechanism.Under the cooperation of these mechanisms,in factory rice seeds were dropped onto a paper strip of 4-7 cm width according to the required hill distance and the number of seeds per hill,then the paper strip with seeds was twisted and turned into a seed rope.With this paper made seed rope,the field experiment was carried out finally.Experiments results showed that this machine performed well,the used amount of rice seeds being only 1/2-1/3 of that needed by conventional direct-planting machine,and the rice yield was about 10 000 kg/hm2,being about 1 000 kg/hm2 higher than the control sowed by conventional direct-planting machine.
